The illumination mechanism 5 comprises a light source 51, and the light source 51 is matched with the curtain mechanism 3.

The loading and unloading mechanism 6 can be fixed independently of the frame 1 in view of the stability of the whole system. Alternatively, the loading and unloading mechanism 6 can be fixed on the frame 1, so as to reduce the volume of the whole equipment.

Specifically, the rotation mechanism 2 (which may also be referred to as a test rotation tester) is attached to the moving module 4 and is movable on a slide rail of the moving module 4.

When actual test, 360 degrees rotations of camera lens that awaits measuring can be realized to rotary mechanism, at the rotation in-process, can rotate certain angle at every turn, later carry out image acquisition, then rotate once more, until the camera lens that awaits measuring rotatory a week to guarantee that all-round no omission tests, can also replace manual rotatory camera lens simultaneously. Moreover, the rotating mechanism 2 can be used as a standard module in the equipment, and can be moved or installed in a whole group, so that the equipment is more convenient to assemble.

As shown in fig. 3 and 4, the rotating device 2 may further include a protective cover 22, a stand 24, a test module 25, and a focusing module 26 in addition to the lens mount and the rotating device. Fig. 4 is an exploded structural view of the rotation mechanism 2. Referring to fig. 4, the lens mount may be a jig 21, and the rotating device includes a motor 23 and a bracket 24. The protective cover 22 has an opening to expose the lens 8 and allow the lens 8 to be taken out or placed. The driving wheel 231 is installed on the motor 23, the driving wheel 231 is driven by the motor 23 to rotate, the driven wheel 241 is installed on the support 24, the driven wheel 241 can be in transmission connection with the driving wheel 231 through a belt and other components (or the driven wheel 241 can also be in transmission connection with the driving wheel 231 through a meshing mode), the jig 21 is installed on the driven wheel 241, when the driven wheel 241 rotates, the jig 21 rotates along with the driven wheel 241, and therefore rotation of the lens 8 to be measured is achieved. The test module 25 is located under the fixture 21, the test module includes an image sensor 251 and other circuits, and the image sensor 251 is aligned with the fixture 21 so that the light passing through the lens 8 can be collected by the image sensor 251.

In the embodiment shown in fig. 3 and 4, the rotating mechanism 2 further includes a focusing module 26, the focusing module 26 includes a lifting motor 261 and a supporting base 262, the testing module 25 is mounted on the supporting base 262, a protrusion or a boss capable of moving up and down may be provided on the top of the lifting motor 261, and the supporting base 262 can be driven to perform lifting movement in the vertical direction, so as to change the distance between the image sensor 251 and the jig 21 (correspondingly, the distance between the image sensor 251 and the lens 8 to be measured is also changed), thereby implementing focusing operation. In the example shown in fig. 4, the support base 262 is generally "T" shaped. In fact, the support seat may have other shapes, and is not limited to the case shown in fig. 4.

Referring to fig. 1 and 2, a part of the slide rails of the moving mechanism 4 is located within a space surrounded by the barrier 11 of the frame 1, in addition to a space surrounded by the barrier 11 of the frame 1. When the rotating mechanism 2 moves to one end of the slide rail of the moving mechanism 4, the rotating mechanism 2 is located outside the space surrounded by the baffle 11 of the rack 1, at this time, the rotating mechanism 2 is close to the loading and unloading mechanism 6, and the loading and unloading mechanism 6 can perform loading and unloading operations (for example, take a tested lens away from the rotating mechanism 2 and place the next lens to be tested). As described above, a part of the slide rail is located within the space surrounded by the baffle 11 of the frame 1, and the curtain mechanism 3 is provided on this side (further, the curtain mechanism 3 may be provided within the space surrounded by the baffle 11 of the frame 1). When the rotating mechanism 2 moves to a position where the slide rail is close to the end, the lens test will be started. Therefore, this position can be understood as a test station, and the rotating mechanism 2 moving to the test station is located in the space surrounded by the baffle 11 of the frame 1, and the optical axis of the lens is directed to the curtain mechanism 3 and the light source disposed in cooperation with the curtain mechanism 3. Like this, the camera lens that awaits measuring can be shot curtain mechanism 3 and the light source that sets up with curtain mechanism 3 cooperation, can accomplish the test based on the image of shooing.

In one embodiment, as shown in fig. 2, the lens to be measured is vertically mounted to the lens mounting part of the rotating mechanism 2, and the curtain mechanism 3 may be located above the rotating mechanism 2 and the moving module 4. When the rotating mechanism 2 moves to the testing station, the curtain mechanism 3 is positioned right above the lens to be tested in the rotating mechanism 2, at the moment, the lens can be shot upwards, and the test can be completed based on the shot pictures.

In other embodiments, the curtain mechanism and the rotating mechanism may also be arranged in a horizontal direction, and at this time, the optical axis of the lens may extend in the horizontal direction, so as to photograph the curtain placed in the horizontal direction and the light source disposed in cooperation with the curtain.

In one embodiment, the moving module 4 may include a slide rail, a motor, and a slide table, which is driven by the motor to move along the slide rail, and the rotating mechanism 2 is mounted on the slide table. The movable module has the advantages of small size, adaptability to narrow space in test equipment and easiness in taking and placing of the lens in the limited space. Alternatively, the mobile module 4 may be a kk module. In other embodiments, the moving module 4 may be other types of motion mechanisms.

As shown in fig. 5, in one embodiment, the curtain mechanism 3 may have a semi-spherical shape (including an approximately hemispherical shape). In the present embodiment, the curtain mechanism 3 has a plurality of holes 31 on the surface thereof, and the holes 31 are used for disposing the light source. Furthermore, the curtain mechanism 3 in this embodiment is not a perfect semispherical shape, but has an opening 32 so that the rotating mechanism 2 mounted with the lens to be measured can be moved in the horizontal direction to the lower side of the curtain mechanism 3 by the moving mechanism 4. In this example, curtain mechanism 3 is located rotary mechanism 2 and moving mechanism 4's top, and during the design, can guarantee that the camera lens is installed on rotary mechanism 2 after with the high parallel and level of curtain mechanism 3's centre of sphere, like this, when testing, moving module 4 can drive rotary mechanism 2 and drive the camera lens and move together to let the measured lens stop in curtain mechanism 3's centre of sphere position, later test. In addition, the holes 31 of the curtain mechanism can be uniformly distributed on the surface of the curtain mechanism 3, and the central included angles of the two adjacent holes are the same. Like this, when the light source set up in the hole of difference, the contained angle between light source and the camera lens optical axis is different, and in addition the camera lens can be rotatory under rotary mechanism 2's drive, so can carry out multi-angle, omnidirectional test to the camera lens.

By adopting the semi-spherical curtain mechanism and enabling the lens to reach the spherical center of the curtain mechanism in the sliding process, the same distance can be kept between the light source and the lens which are correspondingly arranged in different holes, so that under the condition that the lens to be detected is judged to generate stray light, the stray light is eliminated because of the distance difference between the light source and the lens, and the generation reason of the stray light is further facilitated to be determined; in addition, the semispherical curtain mechanism can also effectively shield external interference light, prevent the interference light from irradiating the lens to influence the test result, and ensure the accuracy of the test.

In one embodiment, the light source in the illumination mechanism 5 may employ an optical fiber 51 (which has a higher concentration than conventional LED and incandescent lamps to help improve the detection accuracy), and the illumination mechanism 5 may further include a driving mechanism (not shown) for driving the optical fiber through the hole 31 of the curtain mechanism and performing a reciprocating motion, and the driving mechanism may also control the length of the optical fiber protruding from the hole 31, i.e., the distance between the end of the optical fiber and the center of the curtain mechanism. Because when carrying out the stray light test to the camera lens of different grade type, it is also inequality with the distance requirement between the light source, and through the scheme of this embodiment, can satisfy the distance requirement between the camera lens of different grade type and the light source to test the camera lens of multiple different grade type, and need not to change the equipment of renewal, have better suitability, help reduce cost, reduce test time.

Further, in one embodiment, the number of light sources may be one. As shown in fig. 2, the drive mechanism may now be used to drive the light sources into motion, aligning the light sources with different apertures 31 and reciprocating in the currently aligned apertures 31. Specifically, when measuring, actuating mechanism can at first let light source and first aperture align, according to the type of current camera lens, lets the light source move in the hole, makes the distance between light source and the camera lens satisfy the requirement of this type camera lens, later rotatory camera lens, rotates an angle at every turn, just controls the camera lens and once shoots, and it is rotatory a week until the camera lens. And then, aligning the light source with the second hole, and so on until the test corresponding to all the holes is completed. Since the single light source is used for testing in the embodiment, in order to avoid adverse effects on the test caused by the fact that other holes into which no light source is inserted appear in the shot image, a flip cover can be arranged on each hole, when the light source is inserted into one hole and moves towards the inside of the sphere space of the curtain mechanism, the flip cover of the corresponding hole can be pushed open, and the flip covers of the other holes into which no light source is inserted can be kept closed.

In other embodiments, the number of light sources may be multiple, for example, the number of light sources may be the same as the number of holes 31, and the driving mechanism may simultaneously drive the multiple light sources to align with the holes 31 respectively and drive the multiple light sources to reciprocate in the multiple holes.

Furthermore, in other embodiments, alignment of the light source with the aperture 31, and reciprocation of the light source within the aperture 31 may also be achieved by manual operation.

In addition, the curtain mechanism shown in fig. 5 is provided with a series of holes 31 (in practical application, the number of the holes is not limited to 6 shown in fig. 5), the total length from the first hole to the last hole is approximately a quarter of the circumference of the sphere of the curtain mechanism in the arrangement direction of the holes, the included angles of the centers of the two adjacent holes can be 10 degrees, or the included angles of the centers of the two adjacent holes can be different. This enables testing for stray light at different angles of the field of view, for example, stray light testing of 0 to 170 degrees may be achieved.

In other embodiments not shown, the total length of the first hole to the last hole may be approximately one third of the circumference of the ball of the curtain mechanism. The number of the holes and the central angle between two adjacent holes can be flexibly adjusted, for example, the central angle between two adjacent holes can be 5 degrees, 15 degrees, 20 degrees, 30 degrees, and the like.

In addition, in order to make the test effect better, the inner surface of the curtain mechanism can have darker color, for example, black or dark gray, dark blue, etc., so as to highlight slight veiling glare in the shot image and improve the accuracy of measurement.

Furthermore, in the embodiments described above, the light source is an optical fiber, and the cooperation between the optical fiber and the curtain mechanism is such that the optical fiber is aligned with and capable of reciprocating through the hole of the curtain mechanism. In fact, the cooperation between the curtain mechanism and the light source can be in other ways, not limited to the above, the light source used is not limited to optical fibers, but incandescent lamps or LEDs can be used, and the light source can also be directly mounted on the inner surface of the curtain mechanism.

Optionally, the number of the fixed support 7 can be 3, and the 3 fixed supports 7 can be uniformly distributed on the edge of the curtain mechanism in the circumferential direction of the curtain mechanism, so that the curtain mechanism has better stability in the test process, and the problems of shaking and the like can be avoided. Alternatively, the curtain mechanism may be made of a hard material, and at a position where the curtain mechanism is engaged with the fixing plate 72, the curtain mechanism may be provided with a fixing hole, so that the curtain mechanism may be fixed to the fixing plate 72 by a bolt.
